Abstract: VOX REMOTE UNIT CONTROL IN A CELLULAR SYSTEM of the Invention A cellular radiotelephone system providing service to remote units having a voice operated transmitter (VOX) is disclosed. If the regularly scheduled periodic signal quality measurements made by fixed site equipment indicate that the remote unit signal has not been received for a predetermined number of measurements, an audit request is transmitted to the remote unit. The remote unit responsively keys its transmitter for a predetermined period of time. A first special scan is programmed into the regular process such that the fixed site equipment may continue with its regular process until the signal quality measurement must be made. A second measurement is made following the first and if the two signal quality measurements made while the VOX remote unit is known to be transmitting agree, system reconfiguration for the service of this remote unit may be implemented by the cellular system.

Abstract: A cellular radiotelephone system provides service to remote units having a voice operated transmitter (VOX) (230). If the regularly scheduled periodic signal quality measurements made by fixed site equipment (210, 220, 230, 240, 250) indicate that the remote unit signal has not been received for a predetermined number of measurements, an audit request is transmitted to the remote unit. The remote unit responsively keys its transmitter for a period of time. A first special scan (24) is programmed into the regular process such that the fixed site equipment (210, 220, 230, 240, 250) may continue with its regular process until the signal quality measurement must be made. A second measurement is made following the first and if the two signal quality measurements made while the VOX remote unit is known to be transmitting agree, system reconfiguration for the service of this remote unit may be implemented by the cellular system.
